His quest takes him back to the beginnings of civilization to reveal a startling legacy of religious symbolism and belief which has its roots in the beginnings of a religion of farming, which he reconstructs using computer simulation to explain the latest archo-genetic findings. On Friday 13th Oct 1307 the Knights Templar were struck down in a secret dawn raid by the King of France. Their assets were seized, their members were arrested and they were accused of heresy. So began one of the most mysterious and tenacious conspiracy questions of history.
